Abstract:

In this work, The adsorption of methane onto multi-walled carbon nanotubes (MWCNTs) was studied, in which the influences of temperatureand pressure were investigated. The physical properties of theMWCNT were systematically characterised by Scanning Electron Microscopy (SEM) and Brunauere-Emmette-Teller (BET) surface area measurements. The equilibrium adsorption data were analyzed using threecommon adsorption models: Langmuir, Freundlich and Sips. All of the models fit the experimental results well. The adsorption thermodynamic was carried out at 283.15, 298.15and 313.15 K. The isosteric heat of adosrption( H) was calculated for CH4 and H2, using Claussius–Clapeyron equation. The small amounts of that indicated physical nature of adsorption mechanism.All values were negative, indicating that the adsorptionis feasible and exothermic process in nature
